RANKCONN - Rotary Evaporator – Manual Lifting HR-21M
Brand : Rankconn Instruments
Model : HR-21M
Product Descriptions
The rotary evaporator is mainly used for the continuous distillation of large amounts of volatile solvents under reduced pressure. It is especially suitable for concentrating extracts and distilling the receiving solution during chromatographic separation, enabling the separation and purification of reaction products. The basic principle of the rotary evaporator is reduced-pressure distillation, meaning that during solvent distillation under reduced pressure, the distillation flask continuously rotates.

Product Features
- Manual lifting, simple, stable, and reliable structure; laboratory personnel can easily operate it with one hand.
- LCD display controller, multiple sets of data displayed on one screen, menu-style interface, knob setting: simple, intuitive, and convenient for observation and operation.
- PID controller allows quick and easy setting of rotation speed, temperature, and time.
- Unique inclined double-layer serpentine coil design with a cooling area of 0.15 m²; maximum evaporation capacity up to 22 ml/min, ensuring efficient recovery from small to large sample volumes.
- Double-layer high-efficiency condenser with anti-backflow design; condenser position adjustable.
- Professional sealing system with high-elasticity PTFE sealing rings, featuring high-temperature resistance, corrosion resistance, and durability; reduces the need for frequent replacement compared with traditional seals, extending service life by more than double.
- Dual heating modes (water bath/oil bath) with external heating, making the bath pot easy to clean.
